  Group Pedometer Active Controls
Subjects [n] 148 251 135
Age at enrolment mean [± SD] yr 36.6 [± 12.5]* 40.1 [± 12.6] 39.1 [± 12.0]

Total PA [min/wk] weighted

Total PA [min/wk] unweighted

  1. PA = physical activity; weighted PA calculated by multiplying vigorous-intensity minutes × 2 [24]
  2. SD = standard deviation
  3. * = significantly lower than pedometer subjects (p < 0.05)
  4. # = significantly greater than intervention subjects (p < 0.05).
